Dataset Name:  NumAcc2

Description:   This is a constructed/fabricated data set
to test accuracy in summary statistic calculations.
The numbers are 2-digit floating point values and
differ only in the last decimal place.
Note--by construction, this data set has
 sample mean   =  1.2   (exact)
 sample standard deviation    =  0.1   (exact)
 sample autocorrelation coef. = -0.999 (exact)

Stat Category: Univariate
